Application filed June 21, 1913. Serial No. 775,023.

To all whom it may concern:

Be it known that I, JEANNE MARIE CAN- ,DEL, a citizen of the French Republic, re-

siding in Paris, France, have invented certain new and useful Improvements in Buttons, of which the following is a specification.

This invention relates to an automatic button comprising clamping claws adapted to pass through the material or support in order to engage with and become secured in the male part forming the cap.

This system of button differs substan tially from existing buttons by the fact that the clamping claws are indeformable, their ends, after they have perforated the material or support, being fixed in the interior of the cap with which they have become engaged, by the annular movement of the latter which then locks them like a bayonet joint. In these conditions, the clamping claws can be made rigid and indeformable, while in the existing buttons the claws have to be made of thin metal in order to enable them to be bent, under the action of the pressure exercised on the same, in the interior of the cap in which they expand so as to form clamps. It will be readily understood that in these conditions the button with indeformable claws fixed by a bayonet joint, is of great importance, as it increases the life of the button owing to the strength of the parts securing the cap to the sliding half and moreover makes it possible to secure and to remove the button several times, which cannot be done with the well-known buttons as after a few operations the bent or deformed claws break.

In the accompanying drawing given by way of example Figure 1 shows separately the different parts constituting an automatic button according to this invention, Fig. 2 shows, with parts broken 05, a portion of the button, the sliding half carrying the fixing clamps not being in position. Figs. 3-5 are various views in perspective, with parts broken off, showing the relative positions of the constituent parts of the button while it is being secured. Fig. 6 shows various separate parts of a modified construction of automatic button. Fig. 7 shows in plan, half the back alone, and half the back in which the guide capsule for the clamping claws is placed in position.

According to this invention, the button comprises a hollow head, the back of which is provided with an opening through which the clamping claw or claws secured to the sliding part, are introduced. These clamps are intended to pass through the support, material, etc, in order to secure to it the two constituent parts of the said button which they connect together. The opening at the back is arranged in such manner as to aflord passage to the claws suitably arranged for the purpose, but is such that it looks the latter when the head has been given a suitable angular movement. The claws then. engage with the portions of the back and are exposed to the action of any elastic system arranged in the interior of the head, so that they cannot be separated from the head when under tension, this elastic system acting so as to prevent any accidental angular movement of the parts thus connected.

In the construction shown in Figs. 1-43, the head of the button is constituted by an upper cap a and a back Z), the central. opening 0 of which is surrounded by 'a bead cl formed by folding over the metal. The head (Z is provided with four holes 6 f arranged in pairs on two diameters at right angles. Two of these opposite holes f are moreover extended on the back Z) so as to form in the latter two openings for the passage of the clamping claws. The latter which are diametrically opposite each other are constituted by resilient branches, the

heads of which are provided with collars and form points. These claws g are secured to a sliding part It and can be introduced into the interior of the head owing to the provision of the holes f in the back 5'. By a suitable angular movement of the head, it is then possible to bring the notches 6 pro vided on the head 0? surrounding the opening 0, in front of the points of the claws y, so that the latter, owing to the elasticity of the branches, can engage with them and thus secure together the two independent parts forming the button. Any tension on the said parts having the tendency to separate them, can therefore no longer separate the slide it from the head. The same applies to any accidental rotation, as the clamps g engage with the recesses e of the breech Z) forming a stop. In order however to prevent the claws g from being accidentally separated from the head of the button, either by the bringing together of the two parts constituting the same, which releases the heads of the clamps g from the notches c with which they engage, or by the bringing together of the clamps 9 resulting in the same drawback, there has been arranged, on the one hand, in the interior of the head, any desired elastic system i such as a helical spring or the like, resting on the heads of the claws g by means of a plate j, and on the other hand a protecting cap or socket is which guides the claws g and prevents them from being brought nearer together. In the construction illustrated, the said protecting socket it carries the plate 9' which forms a support for the spring 2' arranged in the interior of the head, and to that end the said plate 7' forms the bottom of the socket is and projects beyond the same on the circumference and is used for connecting the latter to the interior of the head. The button without its slide it carrying the claws, has the shape shown in Fig. 2, that is to say, normally and under the action of the internal spring 2', the plate j rests on the bead (Z which surrounds the opening 0 through which the socket it passes. This socket 7c is provided on its wall with longitudinal grooves Z forming guides and recesses for the clamps g of the slide 72..

For the purpose of assembling, the clamps g of the slide it are brought, after they have perforated the support, into the grooves Z of the socket is whereupon the latter is an gularly moved by means of the slide 71. and clamps g forming spanners, until the point of the claws can be introduced into the openings f provided in the back 6 of the head of the button (Fig. 3). The whole is then pushed home, which results in the spring 2' being compressed, as the clamps 9 push back the supporting plate j and drive the socket 7c. The head of the button is then turned angularly relatively to the slide it (Fig. 4:). The resilient claws are pushed to the side, and their heads engage above the bead d until, when the movement reaches a suitable amplitude, they arrive in front of the stop notches 6 provided on the latter. On the button being released, the expansion of the spring 2' pushes back the socket is until the heads of the clamps 9 have thoroughly engaged with the recesses e where they are thus locked against any accidental angular movement. A reverse manipulation enables the clamps g to be disengaged, and consequently the two constituent parts of the button to be separated. It is obvious that the number of clamps can be varied.

After the head of the button has been moved in the angular direction, the ends of the claws g of the sliding part will engage with the gaps e in the bead forming the edge of the central opening a with which the back I) is provided, so that it is neces sary, in order to avoid the unlocking of the clamps by their coming nearer together, to arrange between them a distance piece. This part is constituted by the guiding capsule is.

In order to facilitate the assembling, the guiding capsule is is, moreover, constructed so as to be locked in the head of the button, so that the longitudinal recesses Z with which the clamps 9 must engage, should be able always to come exactly in front of the notches f of the back, through which the said clamps 9 must pass in order to be put in position. To that end, (Figs. 6 and 7) the collar 7' of the guiding capsule against which rests the spring 2', is provided with small ribs 0- arranged between the corresponding notches. These ribs 0 are intended to engage normally, when the head of the button is separated from the sliding part it, with the notches e or between the locking claws made in the flange on the circumference of the opening 0 of the back 7). In these conditions, the capsule k is locked so that the grooves Z forming guides for the clamping claws g, are arranged on the right of the notches f of the back 5, into which they must be introduced in order to bring about subsequently the fixing and looking as described. The ribs 0 engage for the purpose with the notches e in which they are locked by the spring 2". In that way there is no difficulty in putting the button in place, for when the clamps 9 have passed through the supporting fabric, it is sufiicient to bring them into engagement with the grooves Z of the capsule is belonging to the head, in order to be sure that, by pushing home, the clamps 9 will pass through the openings f provided in the back 6, and will allow the head to be locked. After the angular movement required in order to obtain the result in question, the clamps 9 take the place of the ribs 0 of the collar j with which the capsule is is provided, that is to say they engage between the claws or with the notches e. In that way, for disengaging the button, it is necessary owing to the reverse angular movement given to the head of the button, to bring back the clamping claws 9, after their unlocking, in front of the openings f of the back I); the ribs 0 of the capsule k are thus placed exactly opposite the notches e in the bead forming the edge of the opening 0, so that, when the claws g release the head of the button, the capsule is is again locked in the position which makes the subsequent engagement possible.

What I claim as my invention and desire to secure by Letters Patent is 1. In a separable button comprisingahollow head with an opening therein and a sliding member provided with claws, a projecting bead around the central opening of the head with holes therein to afford a passage for the claws of the sliding member, notches for the final reception of said claws arranged between the holes in the bead, and a guiding socket which can be longitudinally moved in the central opening of the head, said guiding socket having lateral recesses therein which are engaged by the claws of the sliding member.
